chore(bazel): upgrade to latest rules_oci 1.x (#63085)

Upgrades rules_oci from `1.4.3` to `1.7.6`, the latest 1.x release of
rules_oci before upgrading to rules_oci 2.x. Upgrading directly from
`1.4.3` to `2.0.0` is big a jump, because a lot has changed in between.

## Test plan

I don't expect any breaking changes. Also, I am assuming the repo
already has a test coverage for containers built with rules_oci.
